This invention relates to pencils and has to `do more particularly withthat type` wherein leads are clamped in a permanent holder which asusually constructed has a clamping member, non-` removably iixedthereto, in the nature of fa clamping chuck, embodying screw threadedparts co operating with a split sleeve to clamp the lead, and suchclamps are centrally disposed to clamp the lead axially of the holder.In the present invention, a removable clamping member is pro-` videdarranged to slide into the holder and the lead is clamped in an offsetposition with relation to the axis of the holder the latter in the formof a plain tube. And the invention further consists of the novelcombination of parts preferably constructed of any Asuitable materialsuch as `a` highgrade bre board, especially the clamping member of thedevice, which is arranged as a removable part that is slipped out of the`holder to insert or adjust the leads therein and` replaced in the 3claims.` romeo-r9),

holder in a most convenient manner while applyi ing a light pressure onthe clamping member to hold the adjusted position, which pressure is thetube that may vary to suit Vposition in the clamping member beforeentering thesame into the holder, by which through a leverage, action ofthe clamping member a pres` sure is applied to the clamp by the fingersto hold the lead so clamped along the full lengththereof, except theexposed writing end andthe pressure increased when sliding the clampinto the holder.

A further object of the invention, by the con` struction herein shown,all the component parts of the device, except the lead, may befabricated from-,ber-board by use of different thicknesses of thematerial, the clamping member being re- `inforced at parts thereof bycementing two layers i together,` andthe holder formed froma thinnersheet for rolling to form asubstantially sti' tube.

A still further object of the device relates to the offset position ofthe lead-clamping seat with relation to the axis of the tube holder,which provides a lclear view when writing. i i

" As shown my improved pencil is designed to meet the generalrequirements of this art, that isjtofproduce an inexpensive or a moreelaborate article, retaining however the principal features surfaceofwhich it may be 4printed before ,same isrlled to sizeand the end lapcemented to formlthe tube. e e i In Fig. l, I showhowthe pencil willappear in any of the forms of constructionrherein shown. The `tube whichforms the holder, indicated by 2, may be rolled from suitable'paperstock or fiber `board to the dameterbest suited by the number ofconvolutions to form the thickness of the wall and the endlap, 2',`cemented in any The invention will be better understood with A otherobjects thereof disclosed in the following description, forming a partof this specification.

well known manner, andthis end lap before the tube `isfrolled, vup maycontain printed matter thereon as shown. 'I'he tubular holder 2,vprefer-A ably` somewhat the usual `size of the standard pencil,provides` a sizeable opening 3 throughoutl itsIength. 'Ihe holder mam-ofcourse, be constructed of metal or a plastic, material,as anintegraltube.

The clamping member 4 as indicated in Figs. 2 and` 3, on. a largerscale,shows this member con--` structed of fiber-board of suitable thicknessin in Figs. 2 and 3, the outer wall of the circular part of the clampengages theq inner wall of the another feature, sinc the lead is offsetfrom the axis of the holder, the user has a clear View of the writingpoint as shown in Fig. 8.

Having described my invention, I claim:

l.` In a pencil of the, type described, the combination including atubular holder, a removable lead clamping member arranged' to slide intothe open end of the tube holder to engage the inner wall thereof, saidclamp member formed of builttube at the top while the depending arms 'lreach` l0 UP layers 0f ber-bard jhed together 150 1@- downward to theopposite side of they tube topro-` vide room at the ends thereof fortwo'V reinforcing' members 8, which are cementedto the inner faces:

of the depending portions l, to reinforce the same,

inforce the same 'and to form in cross section when folded1 and inposition in the tube for one part thereof in a single layer portion, toform a circular bend appearing in cross section'wof said and the edges 9of the parts 8 are accuratelyl paf-liti llhe` full length thereof, thePSX Of Which placed to conform tothe circular formation of the singlelayer to thereby increase this circulargrip around the lead. The: freeends I of the rei-n forcing members are bent tor extend in oppositedirections and are of a lengthto` yieldingly engage when within the tubeholder 2 about as shown., tof l' engage the center of, thetube asindicated at H. The: depending arms l and reinforcing membersy 8`thereof act like levers to. close the circular part for which a space IZbetween the levers is providedto grip on the lead both when sliding. theclamp member intoV the. tube tothe proper position required', and beforeentering the, tube, the lead may be adjusted in the clamp member, andthis. adjustment maintained by slightly pinching the levers together andthis pressure is increased by the tube, as the clamp member is. gentlymoved therein. y

Figsi and show how the clamping member forms the seat in which said leadis seated,` the outer part of` said circular bend' engaging the isconstructed.v A strip i3 is first. cut to proper 35 width and thecircular groove forming the lead seat is rolled therein, then thereinforced por- I member -is then ready to be trimmed on the' brokenlines indicated at I3, which is then folded and the trimmed edges willconform to the shape shownin Fig. 3.v

In 6, I show the: clamping member folded from. a singley sheet' oflilm-board'of suitable thickness, which is folded as. shown in any wellknown manner in. long length pieces. over a folding rack, after creasingthe paperon. the lines as required, then trimmed to the same shape atthe endsv toA formand length and shape. y

In Fig. 7, I show;the clamp member asv constructed of a ,thinmetal,which need notv be reinforced, the usual practice of forming a blank ofthe proper shape, `which is readily punched, then bending to theformshown, in bendingV dies. This metal type of the device, may .be inthe class of the more expensive type of pencil, highly finished inmanydifferent styles.

All the forms` herein shown have the following advantages over the typesof clamps generally used to hold and clamp thelead.. In my improvedclamping ymember one of these advantages is, the holder tube 2 is plain,no fittings of threaded parts'are required of: anykind. since the clamp,

ing member 4 slides into the open tube to engage the inner wall thereofand the clamp member is readily removed, and the lead is then free to bemoved, toa `new position, sincethe depending lever inner wall of the;tube to be offset from the axis ofthe tube, downward reachingv portionseach side of said circular part and extending toward' the opposi-te:side of the tube, formi-ng lever portions, said lead', and hold' theclamp member in any adjusted position thereof in theI holder.

2. In a pencil device of thetype described, the l combination includinga tubular holderVa lead clamping member arrangedY to 'slide into saidholder to engage, theV inner' Wall thereof,`said nlernb-erA formed ofbuiltup layers of flberl-board joined together'v to reinforce same, toform in a singlelfayer portion thereof as viewed incross secti'orfwhenfolded and ina clamped position within the tube where one part'thelreof,in a single layer portion, is bent to form a circular seat, the

" outer face 4of which engages the inner wall of the tube, downwardextending portionsk of said circular layer part forming lever portionsYreaching downward to the opposite side of the tube; said leversreinforced on Ithe inner sides thereof,

so the-edges thereof conform to saidv circular seat the 'full length of'the clamping member and so retained by a `closing clamping actionapplied -by oppositely- -bent over-hangingv portions of' said reinforcedparts `the free` ends of which engage the contour of the tube inner wallat each. Side to' urge the lever portions together under a yield-l ingactionl of both the tube and the clamp.
